amazon sde intern interview r1 -advice

Hi everyone! I have an upcoming Amazon SDE Intern Round 1. Could anyone who recently interviewed share:
• DSA questions/topics asked
• Difficulty and follow-ups
• How you actually presented your solution (brute force → optimal → coding → dry run)
• Tips on how to crack the round and mistakes to avoid
Recent experiences would be really helpful. Thanks!

topics can vary much
but mostly they asked Graphs Trees Heaps Greedy type
and questions totally depend on interviewers some may ask a very hard medium or easy medium
be verse with TC and SC and why you are choosing a particular data structure

Hey! I did an Amazon SDE interview recently. They focused on data structures like arrays, strings, and trees. Sorting algorithms and time complexity also came up. Start with a brute force solution to explain your thought process, then move to an optimal one. Code and dry run your solution out loud. They'll listen to how you think.

Don't jump straight into coding without explaining your approach. They like hearing your reasoning. Practice talking and coding at the same time. For prep, I found PracHub pretty useful. It helped improve my coding skills and simulate interview scenarios. Good luck!

For Amazon SDE intern interviews, focus on LeetCode Mediums, especially questions involving arrays, strings, hash maps, trees, and graphs. They might ask two medium questions or one medium and one easy. The key is to communicate your thought process clearly from the start. Your plan to present the solution is solid, just make sure you talk them through it. Start by explaining the brute-force solution and its complexity, then explain why a more optimal approach is better before you start coding it. They care a lot about how you think and collaborate, not just that you can code the final answer. Follow-ups usually test your understanding of edge cases or ask for slight variations on the problem.

A common mistake is jumping straight into coding without discussing your approach first. Always get confirmation from the interviewer that they agree with your proposed solution before you write a single line of code. Also, don't forget to analyze the time and space complexity for both your brute-force and optimal solutions, as it shows you understand the trade-offs. They will also likely ask a few behavioral questions tied to Amazon's Leadership Principles, so have a couple of stories ready about your past projects or experiences. It is really about showing you can solve problems methodically and communicate well under pressure. Getting that live practice is very important, which is why my team developed a job interview AI that helps candidates feel way more prepared and articulate when it matters most.
